The new moon is the closest in nearly 1,000 years tonight

Tonight’s new moon may be invisible, but that doesn’t make it any less significant.

It’s not often we get excited about a new moon from a skywatching perspective, given that you can’t see anything from the vantage point of Earth. (New moons occur when the illuminated half of the moon is facing away from us, leaving us seeing nothing but darkness.) But tonight’s new moon is a particularly special one.
